Unit circle is base for trigonometric table . This table consist of ratio, values and angles. It also use for establishing pythagorean identity. Further these identity use in simplification of equations. Hence equation to be solve.

The Unit Circle is probably one of the most important topics in all of Trigonometry Unit circle
Unit circle plays an vital role in trigonometry. The unit circle provide values of T -ratios for given angles. Unit circle worksheet
Unit circle is the source for the generation of the trigonometric function graphs. The quadrants from the unit circle, when placed horizontally in numerical order, create the basis for the trigonometric graphs. Hence This process of creating graphs from the unit circle is often called “unwrapping” the unit circle. Unit circle with Trigo Graph
